Issue

When opening a website, a warning message appears stating that "Certificate verification problem detected" or that "Authenticity of the domain to which encrypted connection is established cannot be guaranteed".

Cause

The website may not be safe. There is a possibility that intruders may steal your account data and other personal information. We do not recommend visiting such websites. 

For detailed information about what can cause the message to appear, see the section below.

Solution

You can allow a one-time visit of a website. See instructions below.  

If you are sure that the website is safe and do not want the application to check it in the future and display warning messages:

  • Add the website that causes the report messages to the exception list. See instructions below.
  • Alternatively, disable the encrypted connections scanning. See instructions below.
